Lowrance Temp Sensor

I have a Lowrance Hook 5 HDI and the last couple of trips out, the temp is way off. I worry because this happened with my last Lowrance unit as well.

"Professionals" that I've spoken with have not been very helpful-insisting that my battery isn't fully charged.

Periodically, I jiggle the connection to my unit and the temp seems to pick up very temporarily.

Wondering if people out there have had similar experiences?
What did you do to fix it?

Many Thanks
